Pilot Officer Charles Edward 'Cas' Casbolt DFM, RAF nos. 565529 (NCO); 47700 (Officer)


'Cas' Casbolt of 80 Squadron at Eleusis, Greece.

Charles 'Cas' Casbolt was born in Southend in 1914 and worked as a shop assistant before joining the RAF.

He enlisted in 1931, becoming a Fitter (Aero Engines) and was later selected for pilot training.

When he qualified as a Sergeant Pilot early in 1938, he joined 80 Squadron. The unit was posted to Egypt shortly after he had joined it.

When the war started in North Africa on 10 June 1940, 80 Squadron was commanded by Squadron Leader R. C. Jonas and based at Amriya. It had 22 Gladiators (mainly Mk.Is) and one Hurricane Mk.I (L1669 – nicknamed Collie’s Battleship) on hand. Its main role was the defence of Alexandria. The pilots were divided into three Flights.
‘B’ Flight included Flight Lieutenant Thomas 'Pat' Pattle, Flying Officer Greg Graham, Flying Officer John Lapsley, Pilot Officer Sidney Linnard, Pilot Officer Vincent 'Heimar' Stuckey, Flight Sergeant Sidney Richens, Flight Sergeant Trevor Martin Vaughan and Flight Sergeant Casbolt.

He saw action over the Desert.

80 Squadron was ordered to Greece and on 18 November the ‘B’ Flight of 80 Squadron left Egypt and reached Athens with at least nine Gladiator IIs led by Squadron Leader William Hickey and including Flight Lieutenant 'Pat' Pattle, Flying Officers Greg Graham and Sidney Linnard, Pilot Officers Samuel Cooper, 'Heimar' Stuckey and William Vale and Sergeant Casbolt.
“A” Flight of 80 Squadron led by Flight Lieutenant Edward Jones left Egypt for Greece on 23 November.

On 19 November 1940, 'B' Flight of 80 Squadron, which recently had arrived to Greece to reinforce the Greek fighter forces, flew up to Trikkala during the morning. After refueling, nine Gladiators took off at 14:10, led by three Greek PZL P.24s (23 Mira), for an offensive patrol over the Koritza area. Squadron Leader William Hickey led the Gladiators.
When they neared the Italian airfield at Koritza the PZLs were obliged to turn back due to their short range. The Gladiators flew over Koritza were Italian anti-aircraft opened up. Flight Lieutenant 'Pat' Pattle, who were leading the second section, sighted four Fiat CR.42s climbing towards them from the starboard beam.
It had been arranged beforehand that the Gladiators would not use their radiotelephones unless it was absolutely essential, because they had discovered in the desert that the CR.42s used a similar wavelength; by listening in to the Gladiators, the Italians received prior information of an attack. Pattle warned Hickey of the presence of the CR.42s simply by diving past the Commanding Officer's section and pointing his Gladiator towards the Italian aircraft. Hickey acknowledged that he understood by waggling his wing and Pattle withdrew to his position at the head of his section.
As Hickey’s section dived towards the four CR.42s, Pattle noticed a second group of two more CR.42s and took his section, consisting of Pilot Officer 'Heimar' Stuckey and Sergeant Casbolt, to engage these. Pattle went for the leading CR.42, which attempted to evade the attack by diving steeply and slipping from side to side. Pattle followed, closing in rapidly, but he didn't fire until the CR.42 straightened out and thereby offered a steadier target. From 100 yards astern, he lined up the CR.42 in his sight and opened fire. The CR.42 steepened its dive; the pilot had apparently been hit, because he fell forward over the control column. Pattle pulled away, as the CR.42 went straight down to crash about two miles west of Koritza, bursting into flames on striking the ground. Stuckey, following close behind Pattle's Gladiator, smiled and gave a thumbs-up signal to Pattle signifying confirmation of the victory.
The two Gladiators, now completely alone, climbed up to 15,000 feet immediately over the airfield, and saw a dogfight in progress a few miles to the north. Heading in that direction, they were soon engaged by five CR.42s and two G.50s. One of the G.50s came at Pattle in a head-on attack, but broke away much too early, the tracers passing yards below the Gladiator. A CR.42 had a go next, but Pattle quickly snap-rolled, up and over the Italian aircraft, and came down perfectly in position fifty yards behind the CR.42. A short burst and the cockpit of the CR.42 became a mass of flames and it fell away burning furiously. After this combat he noticed that his air pressure were so low that he couldn't fire his guns and he soon returned to base.
Totally in this combat the British pilots claimed nine and two probables shot down. Apart from Pattle's two CR.42s, Stuckey claimed one G.50, which crashed, and one CR.42, Flight Lieutenant Greg Graham claimed one G.50 and one CR.42, Pilot Officer Samuel Cooper claimed one shared CR.42 with Pilot Officer William Vale, who also claimed one additional CR.42, Sergeant Casbolt claimed one G.50 and finally Flying Officer Sidney Linnard claimed two CR.42s as probables.
Pilot Officer Stuckey was hit in the combat by CR.42s and wounded in the right shoulder and leg. He was saved from being finished off by Squadron Leader Hickey, who managed to driving away the CR.42s and then escort him back to Trikkala from where he would be dispatched to the Greek Red Cross hospital in Athens.
Pilot Officer Vale reported:

"Nine Gladiators and three PZLs took off from Trikkala in four flights of three aircraft to carry out an offensive patrol over Koritza. I was flying in the second flight as No.2 to F/Lt Pattle. We arrived over the area at approximately 1440 hours and after patrolling for about five minutes two CR42s were seen approaching our formation at 14,000 feet from starboard ahead. The signal for line astern was given by the flight leader, who immediately attacked the enemy aircraft, which broke formation. F/Lt Pattle engaged one CR42 and after a shot dogfight shot it down out of control, with smoke coming from the engine.
The other CR42 was engage by No.1 Flight. I tried to regain my flight but finally attached myself to two Gladiators in formation, which I found out to be No.1 Flight led by S/Ldr Hickey. We carried on the patrol at about 10,000 feet over Koritza, where we met fairly accurate AA fire. ‘Tally-ho!’ was then given when three CR42s in formation were seen at about 6,000 feet. The formation split up and I dived on a CR42 which was attempting to escape to the north. I carried out a quarter attack and then slid in to an astern position, which I held while the enemy pilot did evasive tactics. He then carried out a manoeuvre which appeared to be a downward roll and I noticed that smoke was coming from his engine. I carried on firing in short bursts until he went between two hills through a small cloud. I followed over the cloud but no enemy aircraft appeared and so I went below into the valley and saw wreckage in a copse – at the same time getting fired at by enemy troops.
I climbed up immediately and at 6,000 feet saw a shiny monoplane with radial engine diving down. I gave chase but was out-distanced and so gave up after firing a short burst at about 400 yards. I gained altitude and observed a Gladiator and a CR42 in a dogfight very low down over the hill, and also noticed that the enemy pilot was attempting to lead the Gladiator over a group of enemy ground forces. I waited until the Gladiator pilot had manoeuvred into an astern attack and then carried out a quarter attack. I noticed that first white smoke and then black was coming from the engine of the e/a before I opened fire. I carried out quarter attacks until the other Gladiator pilot pulled away and then slid into an astern attack.
I remained in that position until very low over the main road and then the CR42 turned over and slid into the side of a hill. The aircraft did not burst into flames. While pulling up I fired at the enemy ground troops. I gained altitude and waggled my wings for the other Gladiator pilot to join me and then found the other pilot was P/O Cooper, who had apparently run out of ammunition. I then set course for home and finally landed at Eleusis, where I refuelled, before proceeding to the base aerodrome. I inspected my aeroplane and found that I had one bullet hole in my tail plane, which had done no damage. In each encounter with CR42s I found that both pilots used the downward roll manoeuvre at high speed for evasive action."
80 Squadron had been involved in combat with Fiat CR.42s of 160o Gruppo Autonomo C.T., which were patrolling over this area, and with G.50bis from 24o Gruppo Autonomo C.T., which were escorting bombers in the same area.
In fact, when the British aircraft arrived over the front there were four CR.42s of the 160o Gruppo led by Tenente Torquato Testerini (CO 393a Squadriglia) and two G.50bis of the 24o Gruppo led by Tenente Attilio Meneghel (355a Squadriglia) in the air. The Fiat of Sergente Maggiore Natale Viola (363a Squadriglia) was attacked by a reportedly “20 Glosters and three PZL” and shot down, the pilot being killed while Meneghel attacked six Glosters alone before being shot down himself and killed. It is possible that Sergente Maggiore Viola was shot down by Flight Lieutenant Pattle.
From Koritza airfield, the eight remaining combat ready CR.42s of the 160o Gruppo were scrambled at 15:25 to help their comrades. They were led by Capitano Paolo Arcangeletti but were taken at disadvantage while climbing by the aggressive Glosters losing two more of their numbers when Maresciallo Giuseppe Salvadori (363a Squadriglia) and Sergente Maggiore Arturo Bonato (393a Squadriglia) were killed. Sergente Maggiore Walter Ratticchieri was hit early in the fight and wounded in both legs being however able to return to base and land.
Totally three CR.42s (Viola, Salvadori and Bonato) and one G.50bis (Meneghel ) were lost and one CR.42 was damaged (Ratticchieri). Sergente Maggiore Luciano Tarantini claimed a Gladiator shot down, two more being claimed as probables, one by Capitano Paolo Arcangeletti, the other by a G.50bis pilot.

At 10.30 on 21 December 1940 80 Squadron took off from Yanina for the front in Greece. They were led by Squadron Leader William Hickey and flew in three sections. The first comprised four aircraft and was led by Hickey, the second of three was led by Flight Lieutenant ’Pat’ Pattle and the third trio was led by Flying Officer Sidney Linnard.
Near Argyrokastron three enemy trimotor bombers were seen. They were identified as S.79s, and then three more aircraft with twin tails were seen, recognised in this case as Fiat BR.20s. All six were in fact Cant Z.1007bis aircraft from the 47o Stormo B.T. from Grottaglie. The Italian bombers were attacked by the Gladiators and Pattle believed that he had hit one.
At this moment however 15 CR.42s of the 160o Gruppo appeared on the scene. Maggiore Oscar Molinari, the Gruppo commander, was leading these Italian aircraft on an offensive reconnaissance over Yanina, Paramythia and Zitsa. Seeing the bombers under attack by an estimated 20 Gladiators, the Italian attacked, joined by other aircraft from the 150o Gruppo so that 80 Squadron pilots assessed the number of their opponents at 54!
After 25 minutes the air battle broke up and eight of the British pilots returned to claim eight confirmed and three probables. Pilot Officer 'Bill' Vale claimed three, one of them in flames. Sergeant Casbolt claimed one, which blew up, and another, which spun down (later down-graded to a probable). Sergeant Donald Gregory claimed another two, again one in flames, but his own aircraft was badly shot up and he was wounded in the right eye. He however managed to return to Yanina. Pattle and Flight Sergeant S. A. Richens also claimed one CR.42 each, Pattle reporting that his victim fell in flames, whilst Flying Officers W. B. Price-Owen and F. W. Hosken both claimed probables. However Flying Officer A. D. Ripley in N5854 was seen to be shot down in flames and killed, while Squadron Leader Hickey was spotted bailing out of N5816; sadly his parachute caught fire, and he died from injuries soon after reaching the ground. Greek troops recovered the bodies of both pilots. Flying Officer Sidney Linnard's aircraft (N5834) was also badly hit and he was hit in the left calf by an explosive bullet and was taken to hospital after landing at Yanina.
In return the 160o Gruppo pilots claimed six Gladiators, two each by Maggiore Molinari and Tenente Edoardo Crainz (in CR.42 '394-7'), and one apiece by Tenente Eber Giudici and Capitano Paolo Arcangeletti. Probables were claimed by Tenente Torquato Testerini, Sergente Maggiore Francesco Penna and Sergente Maggiore Domenico Tufano. The 150o Gruppo pilots claimed two more Gladiators in collaboration, while 47o Stormo gunners claimed one more and a probable. As in the case of the British fighters, actual Italian losses totalled only two aircraft, Tenente Mario Gaetano Carancini and Tenente Mario Frascadore of the 160o Gruppo being lost, while Maggiore Molinari was wounded in the right foot and force-landed near Tepelene with a damaged engine.

On 28 January, Squadron Leader Edward 'Tap' Jones led 15 Gladiators from 80 Squadron on an offensive patrol between Kelcyre and Premet.
At 14.20 four 37o Stormo BR.20s and five 35o Stormo Z.1007bis were sighted, and Flight Lieutenant 'Pat' Pattle’s section of three (Pattle, Sergeant Casbolt and Pilot Officer Eldon Trollip) engaged one of the latter unit's new aircraft in a line-astern attack, which fell in flames, only two members of the crew managing to bale out. Casbolt then attacked a second Cant, while Pattle and Trollip went after one of the BR.20s. The Fiat was seen to go down gushing smoke from its starboard engine, disappearing into the clouds covering the mountains near Premeti and was claimed as a probable. Flying Officer Nigel Cullen also reported shooting down a Z.1007bis, which exploded in midair, but as only one was actually lost it is presumed that he also fired at the aircraft shot down by Pattle’s section. One other Cant in another formation was damaged and returned with three wounded aboard - presumably the second bomber attacked and claimed damaged by Casbolt.

At 10:30 on 9 February 1941, Squadron Leader "Tap" Jones led off 14 of 80 Squadron's Gladiators on an offensive patrol over the Tepelene area. They took off in four sub-flights led by Jones, Flight Lieutenant "Pat" Pattle, Flying Officer 'Shorty' Graham and Flight Lieutenant "Timber" Woods. During the take-off Flying Officer W. B. Price-Owen, in the last section, experienced engine stoppage as his Gladiator became airborne and he was forced to glide back to the airfield.
Near Tepelene a trio of S.79s were seen, but lost in cloud. It is however possible that Pilot Officer William Vale claimed that he damaged one of these since he did claim one damaged during the day.
Jones took the Squadron round in a wide arc just north of Kelcyre and led them back towards Tepelene. His engine had been running rough for the last fifteen minutes and now it was beginning to vibrate. He called Pattle over the radiotelephone and told him to take over the lead. Then he throttled right back to ease the shuddering. Within a few seconds he was joined by Flying Officer Wanklyn Flower, who was also having trouble with his engine and together they flew back to Yanina.
Meanwhile, the Squadron continued their patrol and just before midday five CR.42s were seen far away off the port beam by Pattle, followed by many more, 30-40 being reported. In fact there were just 16 fighters of the 150o Gruppo, led by Capitano Edmondo Travaglini, commander of the 365a Squadriglia. The Italian pilots also overestimated the opposition, identifying the eleven Gladiators as 20 strong.
Many individual dogfights developed between Tepelene and Argyrokastron. Pattle shot down one Fiat CR.42, which crashed into the ground at speed on the outskirts of Tepelene, while Flying Officer Nigel Cullen put four bursts into another and reported seeing it crash into the hillside and burst into flames. The Squadron returned to claim four definitely shot down and three probables, but the Greek authorities provided confirmation next day that all seven had crashed, and victories were credited to Flight Lieutenant George Kettlewell, Pilot Officer Vale, Pilot Officer C. H. Tulloch, Sergeant Donald Gregory and Sergeant Casbolt, as well as Pattle and Cullen.
Pilot Officer Vale reported:

"I was slightly behind the main formation … I observed about six or more formations of five CR42s [each] above us and so I gave ‘Tally-ho!’ and I immediately climbed. A dogfight started and from my position the policy of the e/a seemed to be diving attacks and gaining height straight away. One CR42 dived on me from above but I managed to evade his fire by pulling round and up towards him. I fired a short burst, which seemed to scare him away. I then saw a CR42 diving down on another Gladiator and so carried out a diving quarter attack and he pulled away, which left me in an astern position close in. I carried on firing until the e/a turned over on its back and the pilot left the machine. I saw his parachute open and so gained height and fired a long burst at a CR42, which dived down on me from above. I then broke away from the combat and owing to shortage of ammunition and fuel returned to base with F/O Cullen, who came up and formatted with me. We landed at 1240 and on inspecting aircraft found no damage.
The initial claims had been nearer the truth, for four CR.42s were in fact hit. Sergente Romano Maionica (365a Squadriglia) and Sergente Danilo Birolo (364a Squadriglia) both failed to return, the latter being believed to have baled out (Maionica was KIA and Birolo landed in Yugoslavian territory), while Tenente Enzo Rovetta (364a Squadriglia) was wounded and crashed while attempting to land at base, and Capitano Travaglini force-landed near Tirana. In return, the Italians claimed four Gladiators destroyed and nine damaged. 364a Squadriglia pilots Tenente Alberto Spigaglia, Sottotenente Pasquale Faltoni and Maresciallo Ugo Guidi were each credited with a victory.
Flying Officer F. W. Hosken baled out of Gladiator N5811, wounded in one leg, when his controls were shot away and he came down near Tepelene. Flight Lieutenant Kettlewell force-landed Gladiator N5858 some 50 miles north of Yanina due to lack of oil pressure, but with his aircraft undamaged. Both returned to Yanina aided by the Greek army.

On 10 February Italian bombers of all types made sustained attacks on Yanina. Fighters of both the EVA and the RAF patrolled and intercepted in a series of rather confused engagements. During the morning three formations of 47o Stormo Z.1007bis and five S.79s from the 104o Gruppo attacked Yanina. The latter formation were escorted by 154o Gruppo CT G.50bis fighters, led by Maggiore (CO) Eugenio Leotta. This formation was intercepted by a trio of 21 Mira Gladiators, but the escort were on them like a shot, Maggiore Leotta claiming one shot down and his pilots a second in collaboration. The Greek unit only lost one aircraft when Anthyposminagos (Second Lieutenant) Anastassios Bardivilias was shot down and killed.
Three Gladiators of 80 Squadron ('Pat' Pattle, Greg Graham and P. T. Dowding) had chased five Z.1007bis bombers during mid morning (probably a formation from 47o Stormo), but could not gain sufficient height to make an effective attack. Nevertheless they saw their fire strike two of the bombers, Flight Lieutenant Pattle claiming one damaged. During these morning raids bombs fell on the west and north sides of the airfield, but little damage was caused other than to one staff car.
The afternoon was practically a continual air raid alarm. Four S.79s of 104o Gruppo attacked under escort by a dozen 154o Gruppo G.50bis, the escort claiming a further Gladiator shot down when a single Allied fighter of this type intercepted. Ten more 47o Stormo Z.1007bis crews reported attack by ten Gladiators and seven PZLs, claiming four Gladiators shot down. However seven of the bombers were hit, one of them badly, and a number of aircrew were wounded. Fourteen RAF Gladiators, from 80 Squadron and two from 112 Squadron, undertook defensive patrols, during one of which Flying Officer Nigel Cullen chased away one formation of five trimotors, then attacked five more head-on (identified as S.79s) and chased these out to sea, claiming to have shot one down into the sea south of Corfu. Another formation identified as BR.20s, but almost certainly the 47o Stormo Z.1007bis, was intercepted by Flight Lieutenant Pattle, Flight Lieutenant 'Timber' Woods and Sergeant Casbolt, each of these pilots claiming one damaged, while Pilot Officer William Valecaught another which he reported crashed some 15 miles south-west of Yanina. At least five formations raided the airfield during the afternoon, an estimated 150 heavy bombs falling on or near the base. Three 80 Squadron Gladiators were damaged and one 21 Mira fighter was destroyed. In the nearby town much damage was caused and many civilians killed or injured.

Casbolt collected the squadrons first Hurricane in Egypt in February 1941 and flew it back to Greece.

Early in the afternoon on 20 February 1941 eight Gladiators of 80 Squadron and nine of 112 Squadron flew up to Paramythia from Yannina. At 14:45 15 of these Gladiators took off in five sections of three aircraft flying in vic formation, echeloned to starboard and led by Squadron Leader H. L. I. Brown, to escort two Wellingtons of 37 Squadron, flown by Flight Lieutenant M. J. Baird-Smith and Sergeant R. T. Spiller, each carrying about one and a halt tons of supplies. A Greek Ju 52/3m accompanied the Wellingtons and their mission was to drop the supplies to the troops near Kelcyre. Low cloud and rain made the flight difficult, and near Korouode five hostile aircraft were seen, but these did not approach. The supplies were dropped successfully, and the three aircraft were escorted back to Paramythia. The fighters then returned to the frontline to patrol.
Soon after the supply-droppers had gone, 17 Blenheims (eight of 84 Squadron, six of 211 Squadron and three of 30 Squadron) commenced taking off for a bombing attack on Berat. One of the 84 Squadron aircraft suffered an engine failure and belly-landed, but the remaining 16, with an escort of six Hurricanes led by Flight Lieutenant 'Pat' Pattle (Hurricane Mk.I V7724), arrived over the target, their bombs falling on the town, supply dumps, and demolishing a bridge carrying the main road over the River Osem. AA fire was experienced and Fiat G.50bis from the 361a and 395a Squadriglie, 154o Autonomo Gruppo C.T. were scrambled from Berat airfield. As the Blenheim formation, which had completed its attack, was turning a few miles to the north of the target the climbing Italian fighters were spotted by the escorting Hurricanes.
Pattle’s section took on four of the attackers and Pattle shouted to Flight Lieutenant 'Timber' Woods and Sergeant Casbolt to attack individually. Pattle selected the leading G.50 as his own target. As he approached, the dark green Fiat pulled away into a steep turn, but he managed to hold it in his sights until he came into range. When he opened fire the Italian fighter exploded and disintegrated. Woods (Hurricane Mk.I V7138) claimed another and Casbolt claimed two destroyed in this combat. The crews of the Blenheims under attack verified these claims. Pilot Officer Cox's Blenheim L8542 of 211 Squadron was badly shot-up, but two Hurricanes shot down their attacker. Pilot Officer Geary, gunner in Squadron Leader Gordon-Finlayson's aircraft, reported:

‘A G 50 came for us and in a flash a Hurricane just shot it off our wingtip. It simply rolled over, went on fire, and dived into the mountain. It was wizard.’
Other Fiats followed the Blenheims as they withdrew. One of the 30 Squadron Blenheims had its starboard engine shot out, but Sergeant Ratlidge managed to get it back to Paramythia. As the formation neared the front, the patrolling Gladiators of 80 and 112 Squadrons spotted the pursuing Italian fighters and engaged them. Flying Officer Nigel Cullen (Gladiator Mk.II N5817) reported:
‘The leader came into close range and then flicked over on its back and dived down. I did a half-roll and got into position dead astern. Four long bursts and the enemy caught fire and crashed into a snow-covered hill. Then engaged another G.50 and got in some good deflection shots. Saw two formations of biplanes, thought they were Glads and went to take a look at them. They were CR 42s. Got on the tail of one, gave him a burst, and he went over on his back, and the pilot baled out. The others made off at once. Just as well- I hadn't any ammo left.’
Cullen’s Gladiator received some damage during these combats and one bullet furrowed the knuckles of his right hand, but he returned to Yannina without further incident. Three G.50s were claimed damaged by 112 Squadron pilots Flight Lieutenant R. J. Abrahams, Flying Officer Edwin Banks and Pilot Officer Jack Groves. Flight Lieutenant George Kettlewell (Gladiator Mk.II N5917) of 80 Squadron also claimed a G.50, but did not see it crash (thus it was only credit as a probable) whilst Pilot Officer Eldon Trollip claimed another probably destroyed.
The Italian fighters had claimed one Blenheim shot down and one fighter identified as a ‘Spitfire’. Despite the many RAF claims, it seems that only two Fiats were actually lost. Tenente Alfredo Fusco of the 361a Squadriglia was shot down and killed, while Tenente Livio Bassi of 395a Squadriglia was wounded and while attempting to force-land his damaged aircraft at Berat, the Fiat flipped over and caught fire. Bassi, credited at this time with seven victories, was to linger for 43 days before dying in hospital in Rome. A third G.50bis, flown by Sergente Gambetta, was damaged. Both Bassi and Fusco were subsequently awarded posthumous Medaglia d'oro al valor militare.


'B' Flight of 80 Squadron at Yanina, Greece, who together shot down more than 100 enemy aircraft.

On 6 April Germany declared war on Yugoslavia and Greece and immediately attacked.

On 15 April it was decided that 33 Squadron’s remaining Hurricanes would join 30 and 80 Squadrons at Eleusis, while 112 Squadron’s Gladiators would share Hassani with 208 Squadron.

At daybreak on 19 April Luftwaffe reconnaissance aircraft spotted Australian, New Zealand and Greek troops retreating across the Thessaly Plain when they were near Pmokos. Soon some 40 Ju 87s arrived, bombing and strafing, and causing much damage and confusion, and many casualties.
Seven Hurricanes of 80 Squadron, led by Flight Lieutenant William Woods, arrived in the area and promptly claimed four of the Stukas shot down before escorting Bf 109Es of II/JG 27 could intervene. Cheering troops reported seeing at last three of these crash; two were claimed by Pilot Officer William Vale (Hurricane V7134), and one each by Flying Officer P. T. Dowding and Flight Sergeant Rivalant.
Apparently two Ju 87s were lost, one from Stab/StG 2, crewed by Oberleutnant Sebastian Ulitz and Oberfeldwebel Emil Kuklau, which crashed south-west of Elasson with the death of the crew (recorded by the Germans as having been on 18 April), and one of I/StG 3, which crash-landed near Kozani, Leutnant Herbert Wingelmayer being killed and his gunner wounded. The escorting Bf 109s then attacked, two Hurricanes being claimed shot down, one each by Oberleutnant Wilhelm Wiesinger and one by Unteroffizier Alfred Heidel. In fact only Sergeant Casbolt’s aircraft was hit, and he was able to return to Eleusis without undue trouble. Casbolt claimed to have damage one of the Bf 109s, and Flying Officer Eldon Trollip to have shot down one, but no Messerschmitts were hit on this occasion.

By now Squadron Leader Pattle of 33 Squadron was in such a bad condition due to combat fatigue and illness that Squadron Leader Edward Jones, now acting as Wing Commander, Eleusis, ordered him to reduce his flying and to take off only when the air raid alarm sounded. Pattle took him at his word, and was in the air again with Sergeant Casbolt when the alarm went off at 14:50. The two flew around for some time without seeing anything, and became separated before Pattle at last saw two aircraft over Khalkis harbour - Casbolt had found the raiders, and as Pattle watched, the Ju 88 he was attacking went down trailing black smoke. Pattle then spotted another bomber heading north and diving for its lines. Giving chase, he soon caught up and attacked, reporting that it dived into the sea after its crew had baled out.
One Ju 88 was indeed reported lost in this area, 9K+EK of I/KG 51 being lost, although the Gruppenkommandeur, Hauptmann Heinrich Hahn, who was abroad, survived to return to his unit. Asecond Ju 88 from I/LG 1 flown by Hauptmann Siegfried von Eickhorn crash-landed at Salonika due to icing-up, the pilot being injured.

During the day on 20 April Eleusis was almost under constant attack but in the afternoon there was a pause in activity, which allowed a little time for the ground crews to bring the maximum possible number of Hurricanes up to readiness state. Squadron Leader 'Tap' Jones decided that if no further attack had developed by 18:00, all available Hurricanes would undertake an offensive sweep in an effort to raise morale amongst the civilian population of Athens and the surrounding areas, and as a boost to the defenders of Eleusis as well as to the pilots themselves.
However at about 16:45 a formation of 100 plus Ju 88s and Do 17s, escorted by Bf 109s and Bf 110s was reported approaching Athens. The Ju 88s (from I/LG 1) peeled off to make low-flying attacks on shipping at Piraeus, while individual Bf 110s of II/ZG 26 scoured the area, shooting up likely targets. One appeared over Eleusis just as the Hurricanes (nine of 33 Squadron and six of 80 Squadron) were preparing to take off. Fortunately, none were hit, and all took to the air individually, climbed to 20 000 feet and headed for Piraeus, forming sections of two or three en route.
The first trio to arrive over the port, flown by Flying Officers Peter Wickham, Flight Lieutenant Henry John Starrett (RAF no. 40188) and Percival ‘Ping’ Newton (a Rhodesian), caught 15 Ju 88s dive-bombing ships in the harbour (the Greek hospital ship Ellenis was sunk during the attack). The three Hurricanes followed them down and attacked as they pulled out of their dives; Wickham claimed one shot down, whilst Newton claimed two more. Just then Pilot Officer William Vale arrived on the scene, reporting seeing some 30 Ju 88s:

“I carried out eight attacks on the Ju 88s. One caught fire and started going down, so I left him and attacked another. Big chunks broke away from his wings and fuselage, and smoke poured from his engines. He went down vertically. I was then attacked by a 109, but I easily outmanoeuvred him, had a crack at some more, and came home when my ammo was exhausted.”
One Ju 88 flown by Unteroffizier Helmut Benke (L1+ZH) was lost near Athens with all the crew; a second L1+UK, piloted by Oberfähnrich Werner Ziegler, was hit by a Hurricane’s fire and the navigator Gefreiter Heinrich Baumgartner, received three bullets in the head and neck, dying almost at once. The gunners believed that they had shot down the attacking fighter, reporting seeing it fall into the sea near Kalamaki (it was probably the crash of Benke’s Ju 88 they had seen or the explosions of bombs). A second Hurricane then attacked, putting the starboard engine out of action. This was also claimed hit by Gefreiter Hans Baumann (radio operator/air gunner) and was seen making for land. However the Ju 88 was rapidly losing height and although the crew threw out all removable equipment to reduce weight, it ditched in shallow water near Karies, at the foot of Mount Athos. The remaining members of the crew survived the crash. A third Ju 88 suffered engine trouble, but struggled back to Krumovo, where it crash-landed.
The Hurricane hit by Baumann was probably that flown by ‘Harry’ Starrett (V7804), which caught fire as a result. Starrett decided to fly back to Eleusis to attempt to save his aircraft. He made a hard wheels-up landing and the glycol tank blew up, enveloping the aircraft in flames. Starrett managed to get out, but had been very severely burned; he was rushed to hospital but died two days later.
Four more 80 Squadron Hurricanes now joined the battle, Flight Lieutenant William Woods leading Sergeant Casbolt and Flight Sergeant Pierre Wintersdorff (a Frenchman) to attack a formation identified as Bf 110s, but probably composed of Do 17Z from I and III/KG 2, escorted by Bf 110s. Woods carried out two or three separate attacks, believing that he had probably shot down two (but only being credited with one) before breaking off to return to Eleusis to rearm. Wintersdorff claimed one aircraft shot down in flames, which he identified as an ‘Fw187’, but he was then attacked by a Bf 110 and wounded in one leg; his Hurricane was hard hit and he baled out into the sea from where he was soon rescued. Casbolt claimed two aircraft as Bf 110s, but was also then attacked from astern and had his rudder shot away. Breaking away, he encountered a Bf 109 which he reported he had shot down in flames.
Meanwhile the fourth pilot, Sergeant Edward Hewett found himself above six Bf 109s and later reported:
“I dived on the rear one, and he rolled on his back, and crashed to the ground with smoke pouring out. I made a similar attack on a second, and the pilot baled out. I had a go at a third, but didn’t see what happened this time.”
These Bf 109s were possibly from III/JG 77, two aircraft from this unit crash-landing, badly damaged. Three Do 17Zs also failed to return; U5+AL (Unteroffizier Helmut Reim), U5+HL (Leutnant Joachim Brüdern) and U5+AR (Oberleutnant Ludger Holtkampe) were all lost with their crews. Apparently Bf 109Es from 4./JG 27 were also involved in combat at this time, possibly with the 80 Squadron aircraft. Oberleutnant Rödel claimed three Hurricanes shot down in just over ten minutes 16:57, 17:01 and 17:08 (victories nos. 18-20), while Oberfelwebel Otto Schulz (victory no. 6) claimed another at 17:10. It seems that Flight Sergeant Leonard Cottingham of 33 Squadron also claimed a Do 17 in this combat.
At Eleusis the returning Hurricanes were being refuelled and rearmed as swiftly as possible, before climbing back into the fray. Squadron Leader Pattle was by now very ill with influenza, his temperature having been recorded as 103o. Nonetheless he took off for the third time of the day together with Flying Officer Vernon Woodward, following Flight Lieutenant William Woods, who was now off for the second time. Pattle and Woodward had not taken off before, as their aircraft had not been ready. Woodward recalled:
“I took off late with Squadron Leader Pattle - we climbed into a swarm of Ju 88s protected by masses of Messerschmitt 110s. We were overwhelmed. In sun I recall shooting down a 110 off Pattle’s tail, in flames, then probably a Ju 88. Shortly afterwards Pattle got a confirmed Ju 88 (or Bf 110). Subsequently I lost contact with him, then damaged three more 110s, then, being out of ammunition returned tentatively to Eleusis. It was all over – for that day.”
Ahead of Woodward, Pattle was seen going to aid of the Hurricane flown by Flight Lieutenant Woods, which was being attacked by a Bf 110. He opened fire at this aircraft and it was seen to burst into flames (presumably the aircraft Woodward had seem him to destroy), just as Woods’ Hurricane also caught fire and dived into Eleusis bay, killing him. Two more Bf 110s latched onto the tail of Pattle’s AS988, and it quickly began to blaze – there was an explosion, and the wreckage fell into the sea. Flight Lieutenant George Kettlewell arrived on the scene just in time to see the demise of his gallant leader and attacked one of the two Bf 110s responsible, shooting this down into the Bay also. He claimed a second Bf 110 before he too was attacked by yet another Bf 110, and was forced to bale out when V7807 was badly hit. A large and solid man, he landed heavily, cracking two vertebrae in his spine and spending several months in a plaster cast as a result.
Yet another Hurricane was falling to the Bf 110s at this time; Flight Sergeant Leonard Cottingham had claimed three Bf 110s in flames, but he was hit by a fourth and wounded, baling out of his stricken aircraft. The pilots of II/ZG 26’s 5 staffel, led by Hauptmann Theodor Rossiwall, claimed five Hurricanes shot down in this engagement, one each by Rossiwall himself (victory no. 12), Oberleutnant Sophus Baggoe (victory no. 14), Oberfeldwebel Hermann Schönthier, Unteroffizier Fritz Muller and Oberfeldwebel Theodor Pietschmann. However two of the Gruppe’s aircraft were lost in return – 3U+EN (Oberleutnant Kurt Specka) and 3U+FN (Feldwebel Georg Leinfelder), while a third crash-landed with severe damage.

After the withdrawal of the Squadron to North Africa, he was awarded a DFM in August 1941 (gazetted on 22 August) and in September, he was posted to 71 OTU as an instructor.

He was promoted to Temporary Warrant Officer as of 21 December 1941 (gazetted on 17 February 1942)

He was commissioned on 8 February 1942, joining 250 Squadron on 3 April that year.

As of 1 October 1942, he was promoted from Pilot Officer (prob.) to Flying Officer (prob.) (gazetted 18 May 1943).

He was promoted to Flight Lieutenant on 21 December 1943.


Casbolt at the time of his serving with 250 Squadron in North Africa in 1942.

Casbolt ended the war with 5 biplane fighter victories and a total of 13 victories.

He continued to serve in the RAF after the war and on 15 May 1948, his promotion to Flight Lieutenant (on short service) was gazetted with seniority as of 21 June 1946.

On 5 May 1952, he transferred to the Aircraft Control Branch, retaining his rank (gazetted 30 May 1952).

He retired on 21 September 1970, still with the rank of Flight Lieutenant (gazetted on 2 October).

After retirement, Casbolt lived in Australia.

He has now passed away.
